I'PECIFICATION forming part of Letters Patent No. 34:0,532` dated April20, 1886.

Application tiled Scptmihcr 28, 1835. Serial No. 173,491,

To all whom it may concern,.-

Be it known that I, JAMEs F. WILBUR, a citizen of the United States,residing at Richford, in the county of Tioga and State of New York, haveinvented certain new and useful Improvements in Tater Tanks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The object of this improvement is to provide a' water tank with theparts of which it is composed formed and connected to each other in amanner adapted to give great strength to their jointure and greatstrength and durability to the-whole structure. These results areattained by the construction illustrated in the drawings herewith filedas part hereof, in which the same letters of reference denote the sameparts in the different views.

Figure l isa plan View of a water-tank embodying the features of myVimprovement. Fig. 2 is a side elevation of the same. Fig. 3 is a planview of a modification. Fig. 4 is a side elevation of the same. Fig. 5is a representation of a segment of the modied structure. Fig. 6 is arepresentation of a segment having a formation adapted tothe octagonalstructure shown in Figs. l and 2, and provided with dotted curve-linesfor the purpose of more fully illustrating the practicability of themodification shown in Figs. 3 and Lt. Fig. 7 is a sectionalrepresentation of the construction shown in Figs. l and 2, and providedwith dotted curve lines for the purpose of more fully demonstrating thepracticability of the modification illustrated in Figs. 3 and 4. Fig. 8is a representation of a segment of the octagonal structure. Fig. 9 is aview illustrating the practicability of making the structturecylindrical inside and octagonal outside by cutting away the insideedges of the segments of the octagonal structure at suitable curves, andthereby more fully illustrating the practicability of the modificationshown in Figs. 3 and 4.

Referring to Figs. l and 2, A is the bottom of the tank, which is to beset upon a suitable supporting-frame.

B B and C C represent series of segments (No model.)

forming the tank-wall. These segments are made from strips of plank,preferably two inches thick by four inches wide,and provided withtransversely-beveled ends b b', inclined toward each other; or, in otherwords, so beveled that t-he segments may be set together in the ordershown, with one end of each segment against the inside edge, b2, oftheadjoining segment. The segments G G are of ex; actly the sameconstruction, but have one of their ends set against the inside edge ofthe adjoining segments in reverse order or direction tothat of thesegments B B. The lower series of segments are suitably secured to thebottom A,and the several series ofsegments are secured to each other byspikes orscrews,as shown at D. The segments may be made curvedintermediate of their ends, and the structure made cylindrical in form,if desired, which is the object of the modification shown in Figs. 3 andet, in which A is the bottom.

B B are segments having their outside edges curved their entire lengthand part of their inside edges curved and the remaining part straight,as shown at b3 b4 in Figs. 3 and 5, and having one end, b5, beveled atexactly thesame angle as the corresponding ends ofthe segments in theoct-agonal structure, as more fully shown in Figs. 6, 7, 8, and 9, sothat they may be set together in the order shown,with one end of eachsegment against the inside or straight edges of the adjoining segments.

C C are segments of exactly the same construction as the segments B',but have their beveled ends set against the inside or straight edges ofthe adjoining segments in reverse order or direction to that of thesegments B. The lower segments, G', are secured to the bottom A, and theseveral series of segments are secured to each other by spikes or screwsD, as in the octagonal structure.

teferring to Fig. 6, B represents a piece of plank having straight andparallel edges and its ends cut away at angles, adapting the same toforming a segment of an octagonal struct' ure substantially as shown inFigs. 1 and 2, and, as indicated by the adjacent dotted lines, agreeingwith the profile of the piece B and that of an octagonal structure. Bycutting away the body of the piece outside of the dot- IOC tedcurve-lines within the same the piece would form the counterpart to thesegments B, (shown in Figs. 3 and 5,) and a number of such segmentswould therefore go together in the order shown in Figs. l and 2, andform a cylindrical strueture,as shown in Figs. 3 and 4.

Referring to Fig. 7, B B B represent segments of an octagonal tank setItogether substantially in the order stated. By observing the dottedlines in this ligure itwill be obvious that by giving the segmentssuitable curves the parts may be set together in the order shown inFigs. l and 2, and made to form a cylindrical structure.

By cutting away the inside edge, b2, of the octagonal segment B, (shownin Fig. 8,) and curving the same as shown at b3 in Fig. 9, the segmentscould be set together in the order shown in Figs. l and 2, and made toforin a structure with a cylindrical inside and an octagonal outside, asindicated by the dotted lines in Fig. 9, which still more abundantlyelucidates the practicability of the modification set forth.

The special purpose and features of the improvement is not a structureof either Octagonal. cylindrical, or other particular form, but astructure of great strengtlnwhich is attained by the peculiar manner inwhich the parts are set together and the reverse order in which thealternate series otlsegments are set to gether, and thereby making eachof series of segments lap and strengthen the jointures of their adjacentseries.

,ses

The octagonal structure shown in Figs. l and 2 can be made at lessexpense than a cylindrical structure of substantially the samedimensions, as there would be 'no material Waste oflumber in forming theparts. The cylindrical structure would bemorc expensive, for the reasonthat thelumber would cut to Waste in forming the parts, but theadditional expense would be compensated by the increased inside area ofthe cylindrical structure, as indicated by the dotted lines in Figs.6,7, and 9.

Either the octagonal or cylindrical structure herein described isadapted for and could be used as a bin.

Having explained the features of my im- `provement,what Iclaim as new,and desire to secure by Letters Patent, is-

A tank constructed,as herein shown and described, of segments arrangedwith their ends and inner edges set alternately against the ends andinner edges of their adjoining segments, each horizontal series ofsegments hav` ing the saine formation and being arranged iu reverseorder to its verticallyadjacent series in order that each alternateseries of segments may strengthen the joints of the adjacent series, allsecured together by spikes or screws, as and for thepurpose set forth.

In testimony whereof I at'tlx my signature in presence ot' twoWitnesses.
